Arch Linux User Repository

@fbrennan Don't get me wrong I see why the _py=$(pacman -Q python ...) hack is useful, but there are a couple of reasons it shouldn't be in this PKGBUILD by default. It runs afoul of both some Arch packaging guidelines and the way some AUR package helpers handle downloads vs. build environments. Fetching the upstream URL should not require the dependencies on the host system, and querying the host system for versions might run amuck when building in a chroot.

If it's a regular problem I can stick that code in the PKGBUILD in a comment for others to use when need arises. If we get into another dry spell again where upstream is behind locking to an old Python build is certainly an option too, although I think it would require patching to do properly so it could co-exist on a system with more than one python.

Here's a python39-skia:

# If anybody wants to muck around with the Chromium tree and figure out how to
# build skia from source on Arch I'm open to patches, but even after mucking
# around with ninja and Python2 and various patched bulid toolchains I have
# come up short of a way to build this against Arch packages. Drop a comment on
# the AUR page if you have ideas.

package() {
    export PIP_CONFIG_FILE=/dev/null
    warning "Using Python3.9!"
    warning 'The Python3.9 installation you use will need numpy installed separately e.g. `pip3.9 install --user numpy`!'
    python3.9 -m ensurepip

}

Non-functional package due to https://github.com/kyamagu/skia-python/issues/170.

When that is fixed, this package will still be non-functional without this patch:
